In TSSST switch (where SSS stands for a three-stage space-division switch) with N=150.  It is used 15 time division switches in the first stage and 15 time division switches in the fifth stage. We use 3 crossbar switches in the second stage, 2 crossbars at the third stage, and 3 crossbars at the fourth stage. What is the total number of crosspoints?

The connection diagram shows multiple gates and the pins assigned to each gate. For example, from the datasheet connection diagram of IC 7400, four individual NAND gates can be observed. Pins 1, 2 and 3 are all related to one of the four NAND gates. For each gate the top input is assigned the letter A while the bottom input is assigned B and the output is assigned the letter Y. The function tables of the ICs are normally given in terms of H (High logic level) and L (Low logic level). Referring to the datasheet function table of IC 7400 shows the four different input combinations of A and B and the corresponding output Y for one of the four NAND gates. There is also one more letter assignment that could be found in function tables, this is the letter X, a don't care assignment. In cases where an X is given, it can be replaced by either an H or L assignment without effecting the resultant functionality of the IC. An example of this case can be seen for the function table of IC 7402. The…

6. Draw a space-division THREE (3) stages switches. There are 9 inputs and 16 outputs. Stage 1 has three switches; stage 2 has two switches and stage 3 has four switches.

Draw a circuit to implement a switching network with two data inputs (A and B), two data outputs (C and D), and a control input (S). If S=1, the network is in pass-through mode: C=A and D=B. If S=0, the network is in crossing mode: C=B, and D=A. Use the most reasonable combinational building blocks or gates. Label the inputs and outputs.
